Mr. Mariani continued, As we enter 2019, we plan to direct a large portion of our
$60 million capital budget into our previously announced investment in our Bairoil Field, while also funding an increasing level of drilling activity in our non-operated Eagle Ford properties. We are
continuing to evaluate development opportunities in our lease blocks in federal waters offshore California and with our East Texas properties, and have the ability to adjust our budget as the year progresses. Our solid operational and financial
performance in 2018 gives us confidence that we can continue to execute strategically and enhance shareholder value in 2019.

Production Update

During the fourth
quarter of 2018, Amplify produced 142.5 MMcfe/d, which was above the midpoint of our guidance for the quarter due primarily to higher gas production in East Texas. Fourth quarter oil production in the Beta Field fell slightly below expectations, as
certain wells were impacted by the Companys maintenance turnaround that was completed early in the quarter. The Company is continuing its workover program to return down wells to production in the Beta Field.

3

Operations and Capital Spending Outlook

Amplifys capital spend for the fourth quarter was approximately $10 million, in-line with
quarterly guidance. Fourth quarter capital was allocated 67% in the Rockies which included $3 million spent on equipment for the Bairoil plant expansion project and 22% in the Eagle Ford, with the remainder focused primarily on workover and
infrastructure related projects in California and East Texas.

In 2019, we anticipate capital spending of approximately $60 million
across our operating areas. Approximately $34 million of this capital will fund the plant expansion project in Bairoil, which will allow the Company to bring currently shut-in wells back online and
increase oil production by approximately 900 Boe/d. The expanded Bairoil facility is scheduled to be operational by the fourth quarter of 2019, with production increases expected to be fully realized over the subsequent eighteen months.

In addition, the Company participated in 20 gross (1.1 net) wells in the Eagle Ford Shale and Austin Chalk formations which were spud before year-end 2018. Amplifys working interest in these 20 wells is approximately 5.5%. Initial production from some of these wells is expected in the first quarter of 2019, with the remainder expected to be
completed in the second quarter of 2019. As previously discussed, the last 10 gross wells that were brought online in 2018 on our acreage outperformed the Companys internal type curves, with IP-30 oil
production rates averaging above 1,300 barrels per day (gross). The Company anticipates similar results for the current wells and has allocated approximately $12 million in the 2019 capital budget for drilling and completion activity in the
Eagle Ford.

The remaining capital budget of $14 million will be spent predominantly on well work, facilities and other maintenance
activities across our assets.

Utilizing flat pricing of $55.00 per Bbl of oil and $2.75 per MMBtu, Amplifys year-end 2018
proved developed reserves had a PV-10 value of approximately $590 million, which is 50% or $198 million higher than the Companys current enterprise value of approximately $392 million(3). Amplifys total proved PV-10 of $743 million is 90% or $351 million higher than the Companys current enterprise value.

First Quarter and Full Year 2019 Guidance

The following guidance included in this press release is subject to the cautionary statements and limitations described under the
Forward-Looking Statements caption at the end of this press release. Amplifys 2019 guidance is based on its current expectations regarding capital expenditure levels and on the assumption that market demand and prices for oil and
natural gas will continue at levels that allow for economic production of these products. In addition, beginning in 2019, Amplify has elected to change its reporting convention from natural gas equivalent (Mcfe) to oil equivalent (Boe) given the
increasing focus on our liquids-weighted production and development.

This press release includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical facts, included in this press release that address activities, events or developments that Amplify expects,
believes or anticipates will or may occur in the future are forward-looking statements. Terminology such as will, would, should, could, expect, anticipate, plan,
project, intend, estimate, believe, target, continue, potential, the negative of such terms or other comparable terminology are intended to identify forward-looking
statements. Amplify believes that these statements are based on reasonable assumptions, but such assumptions may prove to be inaccurate. Such statements are also subject to a number of risks and uncertainties, most of which are difficult to predict
and many of which are beyond the control of Amplify, which may cause Amplifys actual results to differ materially from those implied or expressed by the forward-looking statements. Please read the Companys filings with the Securities and
Exchange Commission, including Risk Factors in its Annual Report on Form 10-K, and if applicable, its Quarterly Reports on Form 10-Q and Current Reports on
Form 8-K, and other public filings and press releases for a discussion of risks and uncertainties that could cause actual results to differ from those in such forward-looking statements. All forward-looking

any forward-looking statements, whether as a result of new information, future results or otherwise.

Use of
Non-GAAP Financial Measures

This press release and accompanying schedules include the non-GAAP financial measures of Adjusted EBITDA and Free Cash Flow. The accompanying schedules provide a reconciliation

8

of these non-GAAP financial measures to their most directly comparable financial measure calculated and presented in accordance with GAAP. Amplifys non-GAAP financial measures should not be considered as alternatives to GAAP measures such as net income, operating income, net cash flows provided by operating activities or any other measure of financial
performance calculated and presented in accordance with GAAP. Amplifys non-GAAP financial measures may not be comparable to similarly titled measures of other companies because they may not calculate
such measures in the same manner as Amplify does.

Adjusted EBITDA. Amplify defines Adjusted EBITDA as net income or loss, plus
interest expense; income tax expense; depreciation, depletion and amortization; impairment of goodwill and long-lived assets; accretion of asset retirement obligations; losses on commodity derivative instruments; cash settlements received on expired
commodity derivative instruments; losses on sale of assets; unit-based compensation expenses; exploration costs; acquisition and divestiture related expenses; amortization of gain associated with terminated commodity derivatives, bad debt expense;
and other non-routine items, less interest income; gain on extinguishment of debt; income tax benefit; gains on commodity derivative instruments; cash settlements paid on expired commodity derivative
instruments; gains on sale of assets and other, net; and other non-routine items. Adjusted EBITDA is commonly used as a supplemental financial measure by management and external users of Amplifys
financial statements, such as investors, research analysts and rating agencies, to assess: (1) its operating performance as compared to other companies in Amplifys industry without regard to financing methods, capital structures or
historical cost basis; (2) the ability of its assets to generate cash sufficient to pay interest and support Amplifys indebtedness; and (3) the viability of projects and the overall rates of return on alternative investment
opportunities. Since Adjusted EBITDA excludes some, but not all, items that affect net income or loss and because these measures may vary among other companies, the Adjusted EBITDA data presented in this press release may not be comparable to
similarly titled measures of other companies. The GAAP measure most directly comparable to Adjusted EBITDA is net cash provided by operating activities.

Free Cash Flow. Amplify defines Free Cash Flow as Adjusted EBITDA, less cash income taxes; cash interest expense; and total capital
expenditures. Free cash flow is an important non-GAAP financial measure for Amplifys investors since it serves as an indicator of the Companys success in providing a cash return on investment. The
GAAP measure most directly comparable to distributable cash flow is net cash provided by operating activities.
